Injecting after a meal?

Has anyone done this before? I’ve done it once when I’d forgotten to inject before a meal, but could you do it anyway? For example, you’re having a buffet and you eat more than you’ve intended to and you haven’t taken enough insulin. Can you not eat whatever you want and then inject from what you’ve just eaten?
 
Yes you can split your bolus for situations like a buffet, or pizza!
It is generally better to inject before if you do know the carb cojnt you are eating as insulin takes say 20-30 mins to really get going so carbs hit your system before insulin.
 
When you inject after food the food will work earlier than the insulin, resulting in a high spike and than a drop. Injecting before food gives the insulin some time ahead so it catches the carbs as soon as they hit your system (or it should do that in an ideal world. With Fiasp it pretty much does, but with novorapid I had to inject at least half an hour before food to avoid a big spike before the insulin kicked in).
It's up to you if and how often you think it acceptable to have higher bg than nessecary. To me, it's acceptable every once in a while, on a special occasion or with exciting new foods.
With buffet-like meals I simply inject before every new food I pick/get served, so I won't need to know/decide what exactly I'm going to eat. For me, this works a lot better on Fiasp than on NovoRapid, though.
 
When eating a buffet that I have no idea how much I will eat, I tend to split my bolus as @Diakat describes. So I start by taking some insulin for the minimum carbs I expect to eat and then take some more when I go over this in my carb counting.
The other option is to set yourself a carb limit for the buffet.
 
I have just made a pizza from scratch and as I was very hungry after a 6 mike walk in this heat ate the lot (was intending to freeze half!!) injected a small amount 20 mins before I ate. By watching my Libre have had another small dose an hour in and fully expect to have another dose later when that fat delayed spike goes into orbit. In the past I would have thought, ooh yes that amount of carbs will require that amount of insulin, gone hypo an hour later and hyper three hours later. The Libre is a game changer for sugar surfing!
 
I made my BG go really high when I did this and as soon as I returned to injections before meals BG returned to normal.....

Yes @Sonnyb2 That wiĺ happen if you inject all afterwards - but for some fatty meals a split where you inject some first and some after, or if you decide to eat more than expected topping up after is a good idea.
